multiple Grasshopper Elements in Rhino3d gui

first thanx for Grasshopper. it helps me alot in reallife constuction problems.
i want to suggest something wich might be too much or will never be possible in the future.

Could it be possible to implement Grasshopper in this way, that there could be multible Grasshopper elements in the Rhino3d gui. Something like a "Revit Family" but with better flexability. A element which exposes some parameters directly in the Rhino3d Gui and can be instanced and copied.

the second thing i thing would be cool is a kind of parametic drawingtool like the sketcher in Pro/E wich can expose the logic within Grasshopper but is used in the Rhino3d gui.

with best regards

Michael
